Not only does this purifier help to clean out the air for better quality it also comes with a fan and heating features. The controller provided helps make adjusting the settings more convenient as well. The display on the front tells you your room air quality and will notify you if the air quality drops. It was super easy to set up and took less then 5 minutes to start it up. It also comes with QR codes to scan that give you more detailed video instructions and information. I have many air purifiers and this is my favorite! Definitely a must have!
